Effective Reproductive Support for Dairy and Beef Cattle

Product Description

CYSTORELIN® (gonadorelin injection) is a prescription veterinary solution designed to support reproductive health in dairy and beef cattle. It is used for the treatment of ovarian follicular cysts and is used with cloprostenol sodium to synchronize estrous cycles for fixed-time artificial insemination. By stimulating natural hormone release it promotes ovulation and improves breeding efficiency in managed herds.

Benefits

  • Hormonal Activation: Encourages the release of key reproductive hormones like luteinizing hormone and follicle-stimulating hormone to support normal cycling.
  • Cyst Management: Helps in resolving ovarian follicular cysts by triggering ovulation and promoting proper luteinization in cattle.
  • Fertility Support: Contributes to higher conception rates when incorporated into fixed-time artificial insemination protocols with cloprostenol.
  • Administration Flexibility: Suitable for both intramuscular and intravenous use allowing veterinarians to tailor treatment approaches.
  • No Withdrawal Requirement: Does not require milk discard or withdrawal period when administered as per labeled veterinary guidelines.

Frequently Asked Questions

Q1: What is CYSTORELIN used for in cattle?

Ans: CYSTORELIN is used for the treatment of ovarian follicular cysts in milk-producing cattle and to synchronize estrous cycles in both lactating and beef cows. It supports fixed-time artificial insemination programs by stimulating hormone release that leads to ovulation and improved reproductive efficiency in managed herds.

Q2: How does CYSTORELIN work in cattle reproduction?

Ans: CYSTORELIN contains gonadorelin which is a synthetic hormone that functions similarly to the body’s natural GnRH produced in the hypothalamus. It acts on the anterior pituitary to trigger the release of important reproductive hormones such as luteinizing hormone and follicle-stimulating hormone, supporting ovulation and maintaining regular reproductive function in cattle when used under veterinary guidance.

Q3: What is the recommended dosage of CYSTORELIN?

Ans: The recommended dose is 2 ml per cow, providing 100 mcg of gonadorelin diacetate tetrahydrate. It may be given either intramuscularly or intravenously for treating cystic ovaries, and intramuscularly when used within estrus synchronization programs under veterinary guidance.

Q4: Is there a withdrawal period for milk or meat after using CYSTORELIN?

Ans: There is no withdrawal period or milk discard time required when CYSTORELIN is used under veterinary supervision. This allows continued milk production and meat use without interruption, making it suitable for use in commercial dairy and beef cattle operations.

Q5: Is CYSTORELIN safe for use in cattle?

Ans: CYSTORELIN is safe for use in cattle. Research shows no major increase in health issues or negative effects on physiological parameters. It is overall well-tolerated when used according to the veterinary guidelines.
